Like the devices it’s competing with, the SL-1 collects a trove of data about you, but knows it’s too much for you to take in. Consequently, it produces a Q Score, a single 1-100 metric telling you how well you’re looking after yourself and how much fuel is in your tank. As you can see from the screenshot, the score is joined by three other metrics: Sleep, Movement, and Vitality. The latter aggregates your resting heart rate, resting HRV, blood oxygenation level and skin temperature.
Open the app each morning, and you’ll get a pop-up telling you your Q Score
